OT Internet-Exposure AnalyzerShodan / Censys export parser
Paste a Shodan or Censys export of hosts you are authorized to assess, and this tool parses it in your browser to surface internet-exposed operational technology: control-protocol ports that should never face the internet (Modbus 502, DNP3 20000, BACnet 47808, S7 102, EtherNet/IP 44818, IEC-104 2404, Niagara Fox 1911, and more), banners that fingerprint ICS devices and vendors, and no-authentication or default-page indicators. Every host gets an exposure score, results are ranked worst-first, and you can export to CSV or Markdown. This is an analyzer of a pasted export — it does not scan, connect to, or probe any host.
Analyzer, not a scanner. This tool never makes a network request — it only reasons over the export text you paste. That is deliberate: a tool that fetched arbitrary user-supplied targets would be a server-side request forgery (SSRF) risk. Only paste exports for hosts you are authorized to assess.
Paste a Shodan / Censys JSON export, NDJSON, or CSV (ip, port, …)
Parsed entirely in your browser.
